The aim of the study was to evaluate the influence of different temperature control systems on the voluntary feed intake (VFI), percentage of weight loss (PWL) and performance of lactating sows as well as on the weight of their piglets. Two systems were used: traditional temperature control system (TTCS) with curtain management and an evaporative snout cooling system (ESCS). The study was performed during the summer of 2011. After farrowing and at the weaning, 241 sows were weighed to evaluate the PWL during lactation. TTCS sows lost more weight (5.3±0.9%; P<0.05) than ESCS sows (2.2±0.9%). VFI was measured at intervals of four days in 32 primiparous and 39 multiparous sows. ESCS sows had higher VFI (5.8±0.2kg day-1; P<0.05) than TTCS sows (4.8±0.2kg...
